Looking to upgrade your home office or buy supplies for your small business? Check out office-supply stores' Black Friday and Cyber Monday deals. Pro tip: office store sales are also a good place to snag a deal on a stuff you don't actually need for work, like a personal laptop or comfy gaming chair.

Best retailers for Black Friday office deals

Office Depot/OfficeMax is known for its Cyber Week deals (which tend to run Black Friday through Cyber Monday). Its doorbuster deals tend to include laptops, PCs and office chairs. You'll also find deals on less-exciting (but necessary) products like printer paper, flash drives, packing paper, bubble wrap and even coupons for FedEx shipping.

Staples, too, runs a Black Friday sale that features laptops for hundreds of dollars off, computer-and-software bundles, antivirus software and printers. Its sale also includes a slew of gaming and ergonomic office chairs.

Overstock is also a great option for Cyber Monday. The site will offer blowout sales on specific categories, and it usually offers promo codes as well. Its vast selection includes office supplies, office furniture, desk organizers, filing cabinets, desk chairs and so much more.
